Study on Quick Ascertaining Method of Optimal Single Star in Celestial-Inertial Integrated Guidance

单星星光/惯性复合制导能有效提高弹道导弹的机动发射性能和命中精度,在实际应用中需要快速确定最佳星。针对单星平台方案,建立其基于初始定位定向误差的相关数学模型,并采用单纯形调优法实现最佳星的快速确定。仿真结果表明,采用所建立模型能有效修正初始定位定向误差的影响;单纯形调优法选星速度快,精度高,能为有效解决最佳星的快速确定问题提供有益参考。

Single-star celestial-Inertial integrated guidance scheme can improve launch maneuverability and hit precision of ballistic missile. It＇ s necessary to ascertain the optimal-star quickly in application. Based on the initial launch localization and orientation errors, the models of data processing and formulas for correcting missile impact point deviation were deduced; the principle of simplex method for ascertaining the optimal-star quickly was researched. Mathematical simulating results show that the single-star scheme with altered platform can correct the initial errors efficiently, high speed and high accuracy of simplex method is available in ascertaining of optimal star.
